While many studies have examined succession following direct destruction of forests, impacts to plant communities through tephra effects are less obvious, especially where the tephra depth is less than plant height. We used a 33-year experiment in an old growth forest that received shallow tephra deposition in the 1980 eruption of Mount St. Helens (WA, USA), to examine plant communities. We determined if community differences between plots with and without tephra: (1) were detectable, and (2) changed over time. We found that plant communities differed significantly between plots with and without tephra after 33 years. Further, differences were stronger after 33 years than at two years following the eruption. Species richness increased over time in both plots with and without tephra, but live cover was largely stable after two years. Nevertheless, communities shifted in different directions over time, where the changes in species composition and abundance immediately following tephra deposition were inconsistent with net changes that occurred over 30 years afterwards. These results suggest that widespread and apparently minor deposits of tephra, usually interpreted to be of transient importance if any, may induce long-term modifications of understory plant communities.

It is however, threatened by global change drivers such as deforestation and the associated fragmentation of remaining habitat areas, along with increased disturbance and exposure to nutrient inputs from surrounding intensive agriculture. This thesis uses a unique combination of data on plant species occurrence, local environmental conditions and forest spatial extent in order to investigate the ways in which species richness and functional diversity in forest communities are dependent upon local and landscape scale drivers, and to quantify the strength of these relationships. This provides novel understanding of the response of forest plants with different life history traits to the configuration and quality of available habitat, and therefore the way in which understorey assemblages are likely to alter over time following landscape change. Results highlight the importance of local environmental conditions within forest patches but also suggest that patch area and landscape connectivity have an important effect on the trait composition of communities. Preserving large, well connected areas of habitat is therefore likely to be key for the conservation of many species, particularly rarer forest specialists which often possess traits linked to low dispersal ability. Furthermore, there is evidence that species are slow to respond to changes in the spatial extent of habitat. As such, considering the history of forest patches is necessary in order to explain present day patterns in plant species occurrence and to devise effective conservation measures. This highlights the need to integrate understanding of local and landscape scale processes with temporal data in order to properly understand the way in which forest communities are formed and to predict ongoing change under expected global change scenarios.

Plant communities of Italy: The Vegetation Prodrome / Edoardo Biondi in Plant Biosystems, vol 148 n° 4 (2014)  

Public [article]  inPlant Biosystems > vol 148 n° 4 (2014) . - pp 728 - 814 Titre : Plant communities of Italy: The Vegetation Prodrome Type de document : Article/Communication Auteurs : Edoardo Biondi, Auteur ; C.

The Prodrome that is presented in this paper is the first full organic synthesis of the vegetation ofItaly at the alliance syntaxonomic level. It fulfils several needs, the main one being a unified and comprehensive nationalframework that may make an important contribution to the definition of the European Vegetation Prodrome. Syntaxonomy,as well as taxonomy, is sometimes based on considerations that may in part diverge: several authors tend to favour modelsthat are divisive or aggregative to a greater or lesser extent in terms of flora, biogeography and ecology. These different pointsof view stimulate the scientific debate and allow the adoption of a framework that is more widely supported. The Prodromeincludes 75 classes, 2 subclasses, 175 orders, 6 suborders and 393 alliances. The classes were grouped into nine broadcategories according to structural, physiognomic and synecological elements rather than to syntaxonomic criteria. The rank,full valid name, any synonymies and incorrect names are provided for eachsyntaxon. The short declaration highlights thephysiognomy, synecology, syndynamics and distribution of the plant communities that belong to thesyntaxon. The Prodromeof the Italian Vegetation is linked to the European Strategy for Biodiversity, the European Habitats Directive and theEuropean Working Groups related to the ecosystems and their services. In addition to basic applications, the Prodrome canbe used as a framework for scientific research related to the investigation of the relationships between plant communities andthe environmental factors that influence their composition and distribution.

Très répandu sur les placages limoneux du Nord-Est de la France, le Deschampsio cespitosae-Fagetum sylvaticae (Rameau 1996) Renaux, Boeuf et Royer ass. nov. correspond au Poo chaixii-Fagetum sylvaticae Rameau 1996 nom. inval., syntaxon bien connu mais encore non publié de façon valide à ce jour. C’est l’association centrale du Carpino betuli-Fagion sylvaticae Boeuf et Renaux in Boeuf (2010) proposé dans ce même numéro. Le Sorbo ariae-Quercetum petraeae Rameau (1974, 1996) Renaux, Royer et Boeuf ass. nov. est lié aux côtes calcaires avec un déterminisme principal de nature climatique (climat sec des côtes de Bourgogne et régions voisines). Cette association relevant du Carpinion betuli Issler 1931 était méconnue. Quant à la troisième désignée comme Carici brizoidis-Fraxinetum excelsioris (Oberdorfer 1957) Renaux, Boeuf et Royer ass. nov., elle caractérise des chênaies pédonculées sur limons hydromorphes classées dans le Fraxino excelsioris- Quercion roboris Pass. et Hofm. 1968. En plus des bases bibliographiques, nos résultats s’appuient sur l’utilisation de 9 760 relevés répartis à travers la France ainsi que l’utilisation d’un indice de fidélité permettant notamment d’objectiver le choix de la combinaison d’espèces caractéristiques.

The studied area is located in the southern part of Marche Region, Ascoli Piceno Province, under the influence of temperate climate (lower/higher mesotemperate and lower supratemperate bioclimatic belts). The vegetation study has been performed throught 119 phytosociological relevés. All data were submitted to multivariate statistical analysis. The phytosociology analysis has permitted to characterize 6 associations, whereof 2 news: Erico arboreae-Quercetum pubescentis ericetosum arboreae and Hieracio murori-Ostryetum carpinifoliae hieracietosum murori. Chorological and synecological datas were described in the paper, compared to the corresponding associations of the limestones bedrock of the neighbouring area.
